I'd never heard it explained quite that way, great insight! He would understand all of that. This information also may explain why he does so well on most short-ish testing, despite his normal tendency to lose focus. He used to get SO excited to go to school on MAP testing days. It was the only time he got to see material that was difficult for him, new material, and really had to try to figure things out. He always wanted to compete with himself and do better than last time. Then when GT testing at school came (CogAT and Iowa), he was excited to prove himself, and he did. He would leave the house on those mornings like a fighter, amped up, and has always done well. But in the daily work that is now challenging, he really struggles to maintain that level of effort and focus all day every day, and is down on himself about it. He is absolutely capable of doing the work, but he's never had to maintain focus this long, keep it together and be listening all the time. He is also a talented, driven athlete, which was one of your mentions. All good food for thought. Thank you!
